What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Baltic Hermétique Summer

Reviewers highlight the Baltic Hermétique Summer's compact 37mm brushed case with a polished bezel and 150 meters of water resistance. The watch features glossy dials in bright colors with raised BGW9 Super-LumiNova indices that emit a strong blue glow, and it comes with color-matched FKM rubber straps or Baltic bracelets. The Miyota 9039 movement supports hacking and hand-winding. However, the recessed crown can be difficult to manipulate if fingernails are not long enough, and the movement has a stated accuracy of -10/+30 seconds per day. Overall, reviewers praise the Baltic Hermétique Summer for its well-balanced, colorful dials and strong lume at an affordable price point.

Sternglas Sedius

The Sternglas Sedius is widely praised for its harmonious blend of Bauhaus minimalism and Art Deco elegance, featuring a well-balanced sector dial and a smooth-sweeping seconds hand from its Seiko VH31 meca-quartz movement. Owners and reviewers note its pleasing wearability due to the case shape and slender lugs, and it is considered an affordable option with a good price-performance ratio. One reviewer flags legibility issues on the black dial variant, while the blue-on-white offers crispness. The Sternglas Sedius lacks a date complication and features a double-domed sapphire crystal. Overall, owners and reviewers rate the Sternglas Sedius highly for its classy Art Deco aesthetic and value.
